Flexural performance of Hybrid Fiber Reinforced Polymer Concrete using PVA fiber
This paper present the experimental result of flexural behavior of Hybrid Fiber Reinforced Polymer (HFRP) concrete beams reinforced with Glass Fiber Reinforced Polymer (GFRP) rebars and steel bars. This experiment is conducted with the aim of replacing steel reinforcement with GFRP rebars to reduce the risk of corrosion of steel in concrete structures. The data presented in this study is obtained by conducting flexural test experiment on four beams of HFRP beams with various PVA fibre dosage of 0%, 0.25% and 0.5% and one Pure FRP beam. Fly ash is added by 25% in the mix as a mineral admixture to control the shrinkage cracks. The test result showed that by addition of PVA fibre in HFRP concrete enhance the mechanical properties of beam like deflections, ductility, load carrying capacity and flexural capacity. The optimum dosage of PVA fibre is 0.25%. which improve flexural strength by 200% and 31.1% and ductility increased by 112.2% and 55.12% as compared with Pure FRP beam and HFRP beam without PVA fibre.
